$B$-meson decay into a proton and dark antibaryon from QCD light-cone sum rules

Abstract

The recently developed $B$-Mesogenesis scenario predicts decays of $B$ mesons into a baryon and hypothetical dark antibaryon $\Psi$. We suggest a method to calculate the amplitude of the simplest exclusive decay mode $B^{+}\to p\Psi$. Considering two models of $B$-Mesogenesis, we obtain the $B\to p$ hadronic matrix elements by applying QCD light-cone sum rules with the proton light-cone distribution amplitudes. We estimate the $B^{+}\to p\Psi$ decay width as a function of the mass and effective coupling of the dark antibaryon.
